Causes: The values in one of the billing counters, life counter or the scanner counter mismatch between the main side and the engine side.
Remedy: 1 Reinstalling the EEPROM The EEPROM for the different main unit is installed. Execute U004 to check machine serial number at MAIN and ENGINE. If different numbers are displayed, attach the proper EEPROM to the main/engine PWB 2 Replacing the EEPROM The EEPROM is faulty. Replace the EEPROM on the main/engine PWB and execute U004 when C0180 appears 3 Checking the main/engine PWB The connector and FFC are not connected properly or the wire, FFC or PWB is faulty. Clean the terminal of the connectors on the main/engine PWB, reconnect the connector of the wire, and reconnect the FFC terminal. If the wire or the FFC is faulty, repair or replace them. If not resolved, replace the main/engine PWB.
Code: C0190
Description: Backup memory device error
Causes: Data from the FRAM cannot be read at start-up (3 times retries)
Remedy: 1 Resetting the main power FRAM (main/engine PWB) is faulty. Turn off the power switch and pull out the power plug. After passing 5s, reinsert the power plug and turn on the power switch. 2 Checking the main/engine PWB The connector and FFC are not connected properly or the wire, FFC or PWB is faulty. Clean the terminal of the connectors on the main/engine PWB, reconnect the connector of the wire, and reconnect the FFC terminal. If the wire or the FFC is faulty, repair or replace them. If not resolved, replace the main/engine PWB.
Code: C0360
Description: Communication error between the engine PWB and ASIC
Causes: The checksum error appears or the video signal is not reversed when checking the read-back data after transmitting the data. (Successive failure 10 times)
Remedy: 1 Resetting the main power The main/engine PWB does not operate correctly. Turn off the power switch and pull out the power plug. After passing 5s, reinsert the power plug and turn on the power switch. 2 Checking the engine relay PWB The connector and FFC are not connected properly or the wire, FFC or PWB is faulty. Clean the terminal of the connectors on the engine relay PWB, reconnect the connector of the wire, and reconnect the FFC terminal. If the wire or the FFC is faulty, repair or replace them. If not resolved, replace the engine relay PWB. 3 Checking the main/engine PWB The connector and FFC are not connected properly or the wire, FFC or PWB is faulty. Clean the terminal of the connectors on the main/engine PWB, reconnect the connector of the wire, and reconnect the FFC terminal. If the wire or the FFC is faulty, repair or replace them. If not resolved, replace the main/engine PWB.
Code: C0800
Description: Image processing error
Causes: The print sequence jam (J010x) is detected 2 times in succession.
Remedy: 1 Checking the image data The image data is faulty. When this issue occurs only when handling the certain image data, check if the image data is faulty. 2 Checking the situation The printing operation of the certain file is faulty. Acquire the job's log if the phenomenon can be reproduced by specifying the job when the error was detected. 3 Checking the main/engine PWB The connector and FFC are not connected properly or the wire, FFC or PWB is faulty. Clean the terminal of the connectors on the main/engine PWB, reconnect the connector of the wire, and reconnect the FFC terminal. If the wire or the FFC is faulty, repair or replace them. If not resolved, replace the main/engine PWB.
Code: C0840
Description: RTC error ('Time for maintenance T' appears)
Causes: [Check at start-up] • RTC values are old. • Power has not been turned on for over 5 years. • RTC value is older than 2000/1/1 00:01. [Periodic check per 5 minutes after start-up] • RTC values are older than the ones at the last check. • Partial operation by power reset after C840 error and 'Time for Maintenance T' is indicated.
Remedy: 1 Setting the RTC RTC is not properly set. Set the RTC in the System Menu. 2 Checking the life of the backup battery The backup battery has run out. If the same service call error appears after resetting the power, check the backup battery. If it has run out, replace the backup battery on the main/engine PWB. 3 Reattaching the main/ engine PWB The main/engine PWB is not properly attached. Retighten the screws for the main/engine PWB. 4 Checking the main/engine PWB The connector and FFC are not connected properly or the wire, FFC or PWB is faulty. Clean the terminal of the connectors on the main/engine PWB, reconnect the connector of the wire, and reconnect the FFC terminal. If the wire or the FFC is faulty, repair or replace them. If not resolved, replace the main/engine PWB.
Code: C1010
Description: Lift motor error
Causes: After installing cassette 1, either of the following 1 to 4 is detected 5 times continuously. 1. The lift motor excess current is detected for 80ms. 2. The lift sensor does not turn on when passing 10s after installing the cassette. 3. During printing, after detecting the lift sensor off, the lift sensor does not turn on when passing 1s after the ascending control. 4. During motor operation, the lock signal is detected for 1s continuously and it is detected 5 times continuously.
Remedy: 1 Checking the lift plate The lift plate does not operate properly. If the lift plate does not ascend or descend, correct it or replace it. 2 Checking the drive gear The drive gear does not rotate properly. Check if MP lift plate elevation drive gears rotate or have no excessive load. And apply the grease to the frictional parts and repair the related parts so that they can rotate properly. 3 Checking the connection The connector or FFC is not connected properly. Or, the wire or FFC is faulty. Reconnect the following wire connectors and clean the FFC and reconnect. If there is no continuity, replace the wire. If the FFC terminal section is deformed or FFC is broken, replace the FFC. • Lift sensor - Engine relay PWB • Engine relay PWB - Main/ engine PWB 4 Checking the lift motor The lift motor is not properly attached, or it is faulty. Reattach the lift motor. If it is not repaired, replace it. 5 Checking the lift sensor The lift sensor is not properly attached, or it is faulty. Reattach PF lift upper limit sensor. If not repaired, replace it. 6 Replacing the engine relay PWB The engine relay PWB is faulty. Replace the engine relay PWB. 7 Firmware upgrade The firmware is not the latest version. Upgrade the engine firmware to the latest version 8 Main/engine PWB replacement The main/engine PWB is faulty. Replace the main/engine PWB.
